FAQ

Is this converter really free? Yes. Single-file conversion under 1MB is free forever. Batch processing and large files require a one-time $9 Pro license.

Are my files uploaded anywhere? No. Conversion runs entirely in your browser using JavaScript — your subtitles never touch our servers.

Will timing be preserved? Yes. Timestamps are converted losslessly between formats (ASS uses centisecond precision, so timings are rounded down to 10ms precision when converting to ASS).
